Praise: connecting computer and iPhone is easy, in Portrait mode we can see the image of current slide and if we are careful, we can check which slide (build) comes next.

I wish: more possibilities to control the presentation (the most important for me is “Blank Screen” key, obviouslly Apple thinks we don’t need it, because Apple Remote lacks that feature, too) ; you have to manually switch Portrait and Landscape view of the Presenter Display.
